> Just how can we deal with the social issue whereby some people care about preserving the environment, and some just want to demonstrate their cool factor by having rare, 'special' things? I've had a crazy idea for a while: sell certificates for those crazy collectors. The certificates show that the collector has financed x and y to protect species z. The certificates are numbered and traced. Get a couple of celebrities to buy a couple of pre-owned certificates for a higher figure than they were sold originally and hey - we git an instant collectible. (Yes, tongue in cheek; for those who likes blockchains: You can even have your own blockchain for supporting animals..!)
